After having released their new Long Stroke competition offroad engine (BXR LS5PLUS), RB is happy to introduce the new offroad competition engine with the Super Long Stroke technology, the BXR SLS5 V2. The new BXR SLS5 V2 engine is a Super Long Stroke and 5 port engine. This version V2 receives a complete new sleeve with complete new intake port timing and lateral intake port orientation to increase the torque and to have the best end power.

After several tests on different condition’s, the new carburetor is using a double adjustment with an extra spraybar, giving a better idle and is very easy to adjust. This new Super Long Stroke V2 engine provides a very linear acceleration which is appreciated when the track is slippery or bumpy where you need smooth acceleration, but with good torque.
